No, this does not apply to all processor revisions. In early 2014 there was a change in FLASH die in the BF51x family, which required a change in VDD_FLASH from 1.8v nominal to 3.3v nominal. This did not change the processor revision, just the built in flash.

The "old" flash part numbers were labeled ADSP-BF518F, and the "new" 3.3v flash part numbers are labeled ADSP-BF518F16.
